NSB8MTC040-0 Johnson Controls Network Sensor

Overview

The Johnson Controls NSB8MTC040-0 is a high-performance network room sensor from the NS8000 Series designed to manage environmental indoor air quality. It integrates temperature sensing, CO2 monitoring, and passive infrared (PIR) motion detection into a single device without a display. It functions directly with Metasys system Field Equipment Controllers (FECs), Advanced Application Field Equipment Controllers (FACs), Network and Control Engines (NCEs), and Facility Explorer FX-PC series programmable controllers. It is also compatible with Verasys and Johnson Controls Smart Equipment.

Features

• Multiple sensing capabilities including digital temperature, CO2, and occupancy detection.
• Onboard PIR occupancy sensor maximizes energy savings up to 30% by tracking occupancy status and adjusting temperatures accordingly.
• Addressable functionality using BACnet MS/TP protocol communication via the Sensor/Actuator (SA) bus.
• Enclosed in a clean white housing featuring the standard Johnson Controls logo.
• Features dual connection options with standard modular phone jacks and screw terminal strips.
• No local display or setpoint adjustments to prevent unauthorized tampering in public or high-traffic areas.

Specifications

• Temperature Measurement Range: 32°F to 104°F (0°C to 40°C)
• Operating Temperature Range: 32°F to 122°F (0°C to 50°C)
• Operating Humidity Range: 10% RH to 90% RH, noncondensing (85°F maximum dew point)
• CO2 Concentration Range: 0 ppm to 2,000 ppm
• Supply Voltage: 9.8 VDC to 16.5 VDC (15 VDC nominal from SA bus)
• Base Current Consumption: 3 mA maximum (with an additional 15 mA maximum during CO2 measurement cycles)
• Factory Calibration Altitude: 0 ft to 2,000 ft (0 m to 600 m)
• Mounting Options: Switch box or surface mount

Applications

• High-energy usage commercial and institutional facilities looking to minimize operational HVAC costs.
• School classrooms, university dormitories, and educational centers requiring automated ventilation based on CO2 load.
• Office spaces, conference rooms, and hospitality venues leveraging PIR tracking for real-time occupancy trending.
• Corridors and common areas in healthcare facilities and hospitals requiring secure, non-adjustable climate sensors.
